Prerequisites a sense with a listed range
You refine one of your natural senses beyond its usual limits.
Choose one of your senses that has a specific range listed (for example, darkvision 60 feet, echolocation (precise) 30 feet, scent (imprecise) 30 feet, tremorsense (imprecise) 30 feet, etc.).
If the chosen sense is a precise sense (such as vision, darkvision, or precise echolocation), increase its range by 10 feet.
If the chosen sense is an imprecise sense (such as hearing, scent, basic tremorsense), increase its range by 30 feet.
